Tubular carcinoma of the breast: clinicopathologic features and survival outcome compared with ductal carcinoma in situ.

ABSTRACT:

Purpose

Tubular carcinoma (TC) of the breast is an uncommon histological subtype of invasive breast cancer with an excellent prognosis compared with standard invasive ductal carcinoma. Recent studies suggested a possible precursor role for low grade ductal carcinoma in situ (DCIS) in the development of TC. The goal of this analysis was to understand the clinicopathologic features and outcomes of TC by comparing TC with DCIS.

Methods

A retrospective review identified 70 patients with TC and 1,106 patients with DCIS between 1995 and 2011. Student t-test and Fisher exact test were used to compare the clinicopathologic characteristics of TC patients with those of DCIS patients. The Kaplan-Meier method and Cox regression analysis were used to determine disease-free survival (DFS)
